“Driving vehicle all day no problems .it just turned 20,000 miles. Was driving on road when vehicle started surging, like out of fuel, went down road a little further and it happened again .this time I smelled strong diesel fuel fumes. Smoke starting coming out from under hood. . I pulled off road and shut car off. I opened hood lots of smoke and engine compartment completely soaked with diesel fuel ! Had to call roadside assistance. Got towed in to mercedes benz of north haven ct. Service dept today says looks like a rodent chewed something in your engine compartment. …”
